Description

Technical Field

[0001] This utility model relates to the field of skylight technology, specifically a thermally controlled oblique skylight. Background Technology

[0002] Traditional oblique-beam skylights typically employ a design where the light source is attached to a heat sink. Because the casing is completely enclosed, the heat sink cannot have sufficient contact with the outside air, leading to heat accumulation during prolonged operation and difficulty in effective heat dissipation. Secondly, the lights are usually installed at high locations, making it difficult for operators to monitor the equipment's operating temperature in real time, which affects the lifespan of the lights and poses safety hazards. Furthermore, when individual lights exhibit abnormally high temperatures, there is a lack of effective warning mechanisms, making it difficult to detect faulty lights in a timely manner.

[0003] While existing technologies attempt to address the issue by adding temperature sensors, these solutions often require additional detection equipment, increasing costs and potentially damaging the original optical structure of the luminaire. Furthermore, traditional luminaires use simple fixing methods for their heat sinks and housings, resulting in low heat dissipation efficiency and failing to provide clear warning signals under high temperatures. These problems severely limit the safety and lifespan of oblique-illumination skylights. Utility Model Content

[0004] The purpose of this utility model is to provide a heat-controlled oblique illumination skylight, which can improve heat dissipation efficiency, realize automatic high temperature warning, and reduce safety hazards.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a thermally controlled oblique illumination clear sky lamp, comprising a housing, a face frame, a fog blue diffuser plate, a light source, and a heat sink.

[0006] The bottom of the housing is provided with a window, and the radiator is embedded in the window with its outer surface flush with the outer contour of the housing, forming part of the complete outer surface of the housing.

[0007] The housing has an inclined, outwardly convex sidewall portion that forms a non-perpendicular angle with the fog blue diffuser plate;

[0008] The heat-controlled oblique illumination clear sky light also includes a warning component, which is disposed on the inner side of the inclined outward convex sidewall, including:

[0009] Warning light source channel,

[0010] A color-changing card that can be movably installed within the warning light source channel.

[0011] The drive unit that moves the color-changing card.

[0012] In one feasible implementation, the radiator is fixed by screws passing through the side wall of the housing, so that the radiator and the housing form a rigid connection structure.

[0013] In one feasible implementation, the color-changing card is connected to an elastic bending strip, one end of which is fixed to the inner wall of the housing by a fixing rivet; the driving part includes a thermosensitive deformable metal, which is located near the light source and abuts against the bending part of the elastic bending strip.

[0014] In one feasible implementation, the two ends of the thermosensitive deformable metal are fixed between a pair of fixed posts, which are vertically disposed on the inner wall of the housing.

[0015] In one feasible implementation, a guide buckle is provided on the side of the elastic bending strip near the fog blue diffuser plate, and the elastic bending strip can slide linearly on the inner surface of the guide buckle.

[0016] In one feasible implementation, a stop is provided in the warning light source channel, and the stop is located at the end of the movement path of the color-changing card to limit its displacement.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the heat-controlled oblique illumination skylight improves heat dissipation efficiency by flush mounting the heat sink with the housing, and achieves automatic color-changing warning at high temperatures by combining a warning component driven by a heat-sensitive deformable metal, which solves the problems of poor heat dissipation and lack of real-time warning in traditional lamps. It has the advantages of improving heat dissipation efficiency, achieving automatic warning at high temperatures and reducing safety hazards. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 3 This utility model provides a technical solution: a heat-controlled oblique illumination skylight, including a housing 3, a face frame 1, a fog blue diffuser 2, a light source 4, and a heat sink 5. The bottom of the housing 3 is provided with a window, and the heat sink 5 is embedded in the window with its outer surface flush with the outer contour of the housing 3, forming part of the complete outer surface of the housing 3. The housing 3 has an inclined outward protruding side wall, which forms a non-perpendicular angle with the fog blue diffuser 2. The heat-controlled oblique illumination skylight also includes a warning component 6, which is disposed inside the inclined outward protruding side wall and includes: a warning light source channel 61, a color-changing card 62 movably disposed in the warning light source channel 61, and a driving part 63 for driving the color-changing card 62 to move.

[0027] The thermal control oblique illumination skylight provided in this application uses a heat sink 5 embedded in a window at the bottom of the housing 3, making the outer surface of the heat sink 5 flush with the housing 3 to form a complete outline. This maintains the airtightness of the housing 3 while allowing the heat sink 5 to directly contact the air, enhancing heat dissipation efficiency. The obliquely protruding sidewall forms a non-perpendicular angle with the fog blue diffuser 2, ensuring uniform oblique light distribution while creating installation space for the warning component 6. The warning component 6 is driven by the drive unit 63 to move the color-changing card 62 within the warning light source channel 61. When the lamp overheats, the color-changing lens 624 on the color-changing card 62 enters the light path to form a visible warning signal, achieving a visual indication of abnormal temperature using the lamp's own structure. The integrated design of the heat sink 5 and the housing 3 solves the problem of poor heat dissipation in a closed cavity, while the coordinated layout of the oblique sidewall and the warning component 6 achieves a temperature self-warning function without affecting the light distribution. The combination of the two creates a dual technical effect.

[0028] In some examples, the radiator 5 is further secured by screws penetrating the side wall of the housing 3, forming a rigid connection between the radiator 5 and the housing 3. This method of securing the radiator 5 with screws penetrating the side wall of the housing 3 achieves a rigid connection, avoiding the problem of loose contact between the radiator 5 and the housing 3 caused by traditional internal fixing methods. This rigid connection allows the radiator 5 to be fully embedded in the opening of the housing 3 and flush with the contour of the housing 3, maintaining the integrity of the housing 3's appearance while ensuring that the outer surface of the radiator 5 is directly exposed to the air.

[0029] In some examples, the color-changing card 62 is further connected to an elastic bending strip 621, one end of which is fixed to the inner wall of the housing 3 by a fixing rivet 623. The driving unit 63 includes a thermosensitive deformable metal 631, which is located near the light source 4 and abuts against the bent part of the elastic bending strip 621. Through the synergistic effect of the elastic bending strip 621 and the thermosensitive deformable metal 631, an automatic triggering of the warning signal is achieved when the temperature is abnormal. One end of the elastic bending strip 621 is rigidly connected to the inner wall of the housing 3 by the fixing rivet 623, and this end will not deform. The relative deformation occurs on the opposite side. At the same time, its bent part acts as a deformation fulcrum, giving the color-changing card 62 connected to the other end a degree of freedom of directional displacement. The thermosensitive deformable metal 631 is directly arranged near the light source 4 and can sense the temperature change of the core heating area of ​​the lamp in real time. When the temperature exceeds the threshold, the thermosensitive deformable metal 631 deforms and pushes the bend in the elastic bending strip 621, amplifying the deformation using the lever principle and moving the color-changing card 62 towards the warning light source channel 61. This design integrates temperature detection and mechanical drive, eliminating the need for external sensors. Furthermore, by matching the preload of the elastic bending strip 621 with the deformation characteristics of the thermosensitive metal, it ensures that the color-changing card 62 only activates at high temperatures, preventing false triggering. The rigid fixing of the fixing rivet 623 combined with the flexible deformation of the elastic bending strip 621 ensures the stability of the drive unit 63 while adapting to the internal space constraints of the lamp.

[0030] In some examples, the two ends of the thermosensitive deformable metal 631 are further fixed between a pair of fixing posts 632, which are vertically arranged on the inner wall of the housing 3. By fixing the two ends of the thermosensitive deformable metal 631 between a pair of fixing posts 632 vertically arranged on the inner wall of the housing 3, the thermosensitive deformable metal 631 is constrained and positioned. The vertical arrangement of the fixing posts 632 enables the thermosensitive deformable metal 631 to undergo linear deformation along a preset direction when heated, avoiding drive failure caused by displacement of the free end; the fixing method at both ends enhances the controllability of the metal deformation, ensuring that its deformation amplitude is positively correlated with temperature change.

[0031] In some examples, the elastic bending strip 621 is further provided with a guide plate 622 on the side near the fog blue diffuser plate 2. The elastic bending strip 621 can slide linearly on the inner surface of the guide plate 622. By setting the guide plate 622, the movement path of the elastic bending strip 621 is physically constrained, so that the elastic bending strip 621 can only slide in a straight line under the push of the thermosensitive deformable metal 631. The contact surface between the guide plate 622 and the elastic bending strip 621 forms a sliding pair structure, which not only retains the required deformation freedom of the elastic bending strip 621, but also cancels the possibility of lateral deviation of the bending strip through the rigid guide surface. The accuracy of the movement trajectory of the color-changing card 62 is ensured by mechanical limiting, so that the color-changing card 62 can accurately reach the designated position of the warning light source channel 61 and avoid movement deviation caused by irregular deformation of the elastic material.

[0032] In some examples, a stop is further provided within the warning light source channel 61. The stop is located at the end of the movement path of the color-changing card 62 to limit its displacement. By providing a stop at the end of the warning light source channel 61, the movement range of the color-changing card 62 under the action of the drive unit 63 can be effectively limited, preventing it from exceeding the predetermined position due to excessive displacement. The presence of the stop ensures that the color-changing card 62 moves only within a specific area, ensuring that the warning signal can be accurately displayed on the fog blue diffuser plate 2, while preventing it from moving too far and causing structural interference or affecting the illumination effect of the normal light source.

[0033] In some examples, the heat-sensitive deformation metal 631 is a heat-sensitive bimetallic sheet.
